Add Noise
The Add Noise function is a 2D effect that adds random noise to a rendered image.
It is a multi-plugin, consisting of the rendered image contextual menu version that adds noise to a rendered image and the effector version that can be used when rendering animations.
The amount of noise can be set independently for each channel (R, G, B, and Alpha). The rendered image Alpha channel allows you to add noise to only the background or foreground. The effector version has a setting that causes the noise to move randomly in an animation.
